"The cortical veins lie superficially, unlike cortical arteries, and are adherent to the deep surface of the arachnoid mater, thereby keeping the sulci open 1. Cortical veins then drain to the nearest dural venous sinus, such as the superior sagittal sinus (which drains the superolateral surface of the hemisphere) and the straight sinus, to the torcula Herophili, which lies inferiorly (the confluence of sinuses), then to the transverse sinuses, sigmoid sinuses and internal jugular veins 1,2."
